BELT CONVEYER.

Application filed June 4, 1912. Serial No. 701,547.

To all whom it may concern Be it known that I, Brxo'r ADAM ArznL- lUS, a subject of the King of Sweden, and resident of Sandviken, in the'Kingdom of Sweden, have invented certain new and useful Improvements in Belt Conveyers, of which the following is a specification, reference being had therein to the accompanying drawing.

Conveyors for sawdust, coal, ore and other substances, which consist of an endless belt made of leather and india-rubber as is common, are short lived because of the destructible nature of the material of which they are made. Metallic belts (steel belts) are very durable, but metallic belts made in one piece by rolling, cannot, atpresent, be manufactured satisfactorily with a width greater than about 400 millimeters, and furthermore, their-cost rapidly increases with their width.

The object of this invention is to remove the said drawback, by using two or more sheet metal belts located side by side and overlapping'each other at their edges. The

said belts form together in cross section a horizontal, flat or substantially flat, surface, which supports the goods in a manner as reliable as a single belt and without the goods being able to pass through the joints. In this manner the conveyer belt may be made with the desired width so that the belts, mounted edgewise or in a slanting position, which are comn'ionly used to form the side walls of the trough, can be dispensed with, and the complications arising from their use avoided.

In the accompanying drawings, one end of the conveying device in question is shown in a side view in Figure 1, in cross section in Fig. 2 and in a plan view in Fig. 3. Figs. 4, 5, (S are cros sections of the conveyer showing different arrangements of the belt elements, and Figs. 7 views showing the connection of longitudinal sections.

The conveying device consists of three belts 1, 2 and 3. The central belt 2 overlaps the side belts 1 and 3. the tightening of the belts to the necessary degree, special guide rolls 4, 5, 6, may be the belts at one ind or both thcends of the conveying device or supporting the parts of the con and 8 are partial edge For facilitating or other well known veyer at other points, rolls or any other suitable means may be used. Thebelts which compose the conveyer are parallel, the overlapping edges of adjacent parts being in close contact. The top side of the composed belt may, however, be somewhat concave, as shown in Fig. 4. The belts may also be so mounted that the central belt is located with one of its edges under one of the adjacent belts and with its othei edge over the second adjacent belt, as shown in Fig. The same order may be observed whenthree, four or more belts are used. If more than three belts are used, for instance five, they may also be arranged as shown in Fig. (5, the central belt overlapping each adjacent belt, and the said adjacent belts each overlapping the belt adjacent to it. The location of the belts is determined by the manner in which the goods are discharged tromthe conveyer belt.- For instance, it the goods are divided into two parts, discharged at each side of the conveyer by a -shaped scraper 7, Fig. 2, the central belt must be located uppermost at both its edges, and the belts located at the same side of the central belt must be so mounted that each of them is located with its outer edge over the next belt. If all the goods are to be discharged at the one side of the conveyer, each consecutive belt must be located with one edge over'the adjacent belt in the direction in which the goods are moved from the belt, as in Fig. 5, so that no one of the edgtzs can prevent the goods from being discharged and the goods cannot be retained on a belt between the edges of belts adjacent thereto. Also when two belts are used, they are arranged with their adja cent edges overlapping, as in Fig. 5. ()win to the fact that the composed belt has a great width and, consequently, side belts of known form located edgewise may be dispensed with, the present structure has the advantage of permitting the material-being conveyed to be discharged from the conveyer at. any desired point by scraping it sidewise' withoutlifting it from the con veyer.

The belt may be made in two or more pieces longitudinally, connected by means of rivets, as in Fig. 7, or hinges as in Fig. 8,

or approved means. Having now described my invention,
